IVIAGI-IHNE FOR-FORMING PACKAGE-ROLLS OF METALLIC LEAF.

SPECIFICATION forming part of Letters Patent No. 786,953, dated April 11, 1905.

' 'Application filed August 14, 1902. Serial No. 119,672.

To an whom it may concern:

- Be it known that I, WALTER H. Con, a citizen of the United States, residing at Providence,

in the State of Rhode Island, have invented a new and useful Improvement in Machines for Forming Package-Rolls of Metallic Leaf, of which the following is a specification.

1n the manufacture of package-rolls of metalli'c leaf in which the metallic leaf is applied to the paper: strip as it passes under a pressure-roll it is found that the corners of the sheet of metallic leaf are liable to separate from the paper strip and drop therefrom in its passage to the winding-rolls, requiring the operator to stop the machine and replace the sheet by hand, thus losing a considerable amount of time; and it is the object of my inventionto provide means for preventing such delay'and loss; and my invention consists in the employment of a'perforated chamber in connection with air-exhausting means whereby the sheet of metallic leaf will be held in l place by the suction of air through the pores of the paper strip with which the metallic leaf is to be wound."

In the accompanying drawings, Figure 1 represents a side elevation of a machine embodying my improvement. Fig. 2 represents a central vertical section taken in the line 2 2 of Fig. 3. Fig. 3 represents a front end View. Fig. 4 represents a top view. Fig. 5 represents a detail section taken in the line 5 SM Fig. 3, showing the supporting-table for the book of metallic leaf when near its extreme-rearwardposition. Fig. 6 represents a detail section taken in the line 6 6 of Fig.

l 3 with'the table removed and the table-holding bed 'in its extreme forward, position. Fig. 7 represents a transverse section taken in the line 7 7 of Fig. 4. Fig. 8'represents a vertical section taken in the line 8 8 of Fig.

Fig. 10 represents a detail rear view showing the rack and gear for actuatingthe pressing and suction roll. Fig.11 represents an axial section of the pressing and suction roll.

Fig. 12 represents a transverse section of the same. ,In the drawings, A represents the frame of the machine, providedv at its upper end with adhesion of the metallic leaf thereto, passes from the supply-roll D under the tie-rodf of the frame, thence over the tie-rod f, and downward to contact with the inner side of the cylindrical bar of wax I, which .is arranged at the side of the paper strip opposite to the powdered surface. The oppositely-powdered and waxed paper strip passes] thence to the periphery of the pressing and suction roll J, the powdered surface h of the paper strip being on the inner side in contact with the surface of the roll. the waxed surface h of the same being on the outer side. The roll J is secured upon a hollow shaft vi by means of the set-screw i which is held in a hub at the forward end of the roll. The opposite end of the shaft 7 passes through the loose sleeve r1 upon the outer end'of whiclr is secured the gear 11, which engages with the teeth of the rack vi, by means of which the gear i may be actuated in oppositedirections, the said, rack '17 being jointed to the arm 17, which is secured to the loosely-journaled bar 2', provided with the outwardly-extending hand-lever K, by means of which the machine is operated, the said hand-lever being held in its upward position by means of the spiral spring 77, secured at its upper end to the rinder side of the bench B. To theinner end of the sleeve 1?, at the inner side of the frame A, is secured the gear i which engages with the rack-teeth jof the sliding bed L, the said sliding bed being supported between the parallel sides of theframe A upon the parallel' ways j j. The downward and upward movement of the hand-lever K by the operator of the machine will cause a rocking movement of the sleeve 6 and the gear i and a corresponding reciprocating movement of'the sliding bed L. The sliding bed L carries the table M, upon which the book of metallic leaf is to be placed,

in proper position for the attachment of the sheets, singly and properly lapping each other, up'onthe waxed side of the paper -strip G, the

said table M being provided with the down-1 wardly-extending lugs f j ,\to which arev pivoted the bell-crank levers f j, which are loosely held upon the stationary bearing-rods 1' 1"", held in the downwardly-extending lugs ,7' j of the sliding bed L. The saidbell-crank levers f are connected with each other, so as to move in unison, by means of the conmeeting-link j, to the rearward side of which is secured the spiral springj, (shown in Figs.

8 and 9,) the opposite end of the said spiral spring. being secured to the loose l bell-crank lever which, together with the ,loose hellcrank lever j, is held upon the-stationary bearing-rod J At the rearward side of the forwardlyprojecting horizontal arm of the bell-crank lever l; is secured the stud In, which engages with the upper surface of the latch- .cam if, the said latch-cam being pivoted to the inner side of the frame at the point g and held bya suitable stop in its normal position,

as shown in Figs. 5 and '6, and adapted to be raised at its outer end upon the engagement of movement of the sliding bed.

the stud Hwith the incline k at the backward.

The roll J is operated intermittently .bymeansof the ratchet-wheel n, which issecured' lapping contact of the edges of the said sheets upon the paper strip G. When the operatorof themachine depresses the hand-lever K, the sliding bed L and the table M will be carried forward under the roll J until the stud k engages with the incline k atthe outer end of the latch-cam if, thus causing'the'said stud to rise to the top of the said latch-cam, there: by causing the angular movement of the bellcrank lever is, which, through the spiral spring 7", connected with the link i serves to lift the book of metallic leaf held upon the table M to Contact with the paper strip G at the under side ofthe roll J. The spiral spring is attached to the link and-serves to check the downward movement of the table.

At the back of the roll J and ata certain dis-- tance therefrom is placed the stationar'ily-held roll N, provided at its forward end with a gear m, which is connected with the gear m upon the forward end of the roll J by means of the.

The movablev roll N intermediate gear m 15 3ournaled 1n the opposite arms m m, which are rigidly secured to the rod m thesaid rod I being loosely journaled in the sides'of the frame A, so that the-roll N may have an upand-down .movement in the arc of a circle whose center is the axis of the rod m.

the outer end of the arm m is attached the} lthetable M andallowing it to drop to itscord m,which passes over the pulley m and to the pendent end of the cord m is attached the weight m, by means of which a portion of the weight of the movable roll N may be balanced, so as to secure the required degree of pressure upon the package-roll O, which is held for winding revolution between the movable roll N, the stationarily-heldroll N, and the pressingand suction roll J. The movable roll N is provided at its forward end with the gear m which is connected with the gearin/ upon the forward end' of the roll J by meansof the intermediate gear m", held upon the rod of, whichforms the pivoting-axis of the movable roll.

The pressure and suction rollJprovided with the series of perforations p p, through which the air'may be drawn inward from the surface of the roll, and the hollow shaft is provided with a perforation p,through which the airfrom the chamber R of; the roll J may be drawn by means of the-stationary air-exhaust pipe S, which'is supported from the frame A by' means of the bracket '1, the end of the said exhaust-pipe passing into the cavi'ty w of the shaft 71 to-form a tight joint. The exhaust-pipe S may connect with an exhaustfan blower or any other suitable means for 'c'reatin, the, desired rarefaction of the'air withinthe-chamber-R. At the upper side of the roll J is placedthe covering-flap U, which is held upon the rod t-and serves to prevent theair from passing inward through the series of perforations p at the upper side of the roll, which would not be covered by the paper s p in In the operation'of the machine the book I for holding the sheets of metallic leaf is to be clamped upon the table M, so that the back of the said bookwill rest upon the table at about the line '1- in Fig. 4, the backwardlythrown opened leaves of the said book being position. Then/as the hand-lever K is depressed by the operator-the sliding bed L will. be earriedforward under,.the roll J, so that the stud 7c Will-engage with the inclineltat the outer end of the latch-Z0, thus causing the upward movement of'the table, with the attached book of metallicleaf, until the top sheet of metallic leaf strikes against the previouslywaxed under surface of the paper strip G, the said book of metallic .leaf' being then held a yielding pressure, caused by the resilience of the spring j, which serves to maintain the table M in its elevated position under the roll J, and the said top sheet of metallic leaf will thereafter be carried forward in contact with the paperstrip andpressed thereon until the stud is arrives at the pivoted end of the latchcam 70 and drops therefrom, thus releasing against the said paper. strip onthe roll J with former position upon the sliding bed L, the rapidity of the downward movement of the said table being checked by means of the spiral spring 70, which is attached at one end to the connecting-link J and at the other end to the downwardly-extending pin is, which is secured to the under side of the sliding bed. As soon as the table M has dropped to the supportingsurface of the sliding bed L the upward movement of the hand-lever K will cause the backward movement of the sliding bed L and the table M, the stud Z" passing back under the latch-cam H, which latch-cam will be first lifted by the, stud and then allowed to fall to its normal position after. the passage of the said stud beyond the outcrend of the said latch-cam, so that uponthe return movement of the said stud it willagain be raised by the metallic leaf, thus exposing a new sheet which applied sheet upon the succeeding depression Y will be properly applied to the paper stripG and lapped with the edge of the previouslyof the handrlever K, by means of which the exposed sheet of metallic leaf will be first brought to the required point and then raised to contact with the paper strip as before, with its forward edge lapped to the proper extent upon the rearward edge of the previouslyapplied sheet, and this operation will be continued until all the of the said-boot: have been turned and the exposed sheets of metallic leaf attached to the under side of the paper strip Gr upon the roll J and the lapped and attached sheets of metallic leaf have been wound into a package-roll 0 upon the core When the machine for packaging metallic leaf in a roll is being operated without the employment of a suction-chamber, the sheet of metallic leaf is liable to separate from the paper strip G as it rises from the table M to the"package-roll O, which separation requires the stopping of the machineto repair this defeet in the adhesion of the sheet of metallic leaf to the paper strip; 311i) by the employ applied to the back of a supporting paper strip may be made in various forms; Therefore I do not limit my invention to the particular construction described for the safe transference of sheets of metallic leaf from one place to another in a machine, and by my invention sheets of metallic leaf may be wound upinto a package-roll with a supporting paper strip, without the employment of wax or other adhesive material, when desired, the suction pro-' duced being suiiicient to retain the metallic leaf in connection with the paper strip.

I claim as my invention 1. In a machine for putting up sheets offmetallic leaf in connection'with a paper strip, the combinationof means for winding the paper strip and sheets of metallic leaf together upon a core to form a package-roll, and means for. feeding the sheets of metallic leaf onto the paper strip which is being wound, with suction means operating through the pores of the paper strip to hold the metallic leaf thereto in its passage from the feeding means to the winding means fo'r the metallic leaf and paper strip.

2. In a machine-for putting up sheets of inc-- tallic leaf in connection with a paper strip, the I combination of the rolls for winding the paper strip and metallic leaf into a package-roll, and means for feeding the sheet of metallic leaf onto the paper strip, with suction means operating through the pores of the paper strip to hold the metallic leaf thereto in its passage to the winding-rolls.
